Cognition Essay

The article was written based on a study conducted by Smith J., et al. The article describes how the hippocampus deterioration leads to Alzheimer’s – the disease usually targets the memory of the individual, a function of the hippocampus. Physical activity has been shown to preserve the hippocampus, therefore preserving the memory of the individual. If individuals at high risk of developing Alzheimer’s (individuals that carry the genetic marker, ApoE4, for Alzheimer’s) participate in physical exercise, they can lower their risk of developing the disease. Additionally, the article provided viewers with the information about the sample, method and the results. There were 4 groups of participants who were older adults with normal cognitive functioning, aged 65-89. The groups were classified by low/high Alzheimer’s risk and low/high physical activity rates. The sample’s hippocampus and physical activity levels were tracked over the course of 18 months. Furthermore, Science Daily provided an interview with one of the authors, Smith J. and a professor at University of Pittsburgh. The interviews gave insight into the mind of the author, lending a better perspective on the article and providing direct information to

Brain-derived neurotrophic factor (BDNF) is known to increase synaptic efficacy and promote neuronal survival. This protein is also a biomarker for impaired general cognitive function and memory. Studies have bee conducted on mice measuring the concentration of circulating, also called plasma or serum, BDNF in the blood of these animals when they exercise. Exercise has been proven to increase cognitive function and links between a large level of BDNF in the bloodstream and improved results on spatial/ cognitive testing of these rats shows that BDNF correlates to an increase in memory and cognitive abilities. In this research, studies with varying results on BDNF and exercise were taken and summarized in hopes of finding a

A study conducted by Harvard Medical School regarding on how could exercise help your brain and what kind of exercise will help your brain to have a better result. In this article, we learn that exercises can help your brain and can also help your memory. The researchers examined different people to try to understand what exercises could help your brain using 30 minutes section. In this study, the researchers randomly evaluate people doing exercises like cardio and compared their memory and their productivity with those that didn’t any type of exercises.

Participation in physical activity has been shown to have many health benefits for older adults; this study does not provide strong support that it protects against cognitive decline. Reports have been made that physical activity may help guard against stroke and coronary heart disease, both of which may be associated with the development of dementia. Some studies were either limited in their scope or had short follow-up times. In all they find that for older adults, physical activity alone may not protect against cognitive decline.

Research has proven that physical activity improves cognitive function and can also improve brain function throughout a lifespan. Moreover, staying physically active has so many benefits as well. For example, doing exercise and fitness activities help build cells and natural pathways to help reduce changes in memory loss or dementia. Also, it has so many health benefits including long-term improvements to the cognitive function as the young adult reaching mid

Cavanaugh and Blanchard-Fields (2015) state that there is research showing how brain plasticity can be enhanced through aerobic exercise (p.51). It is important that adults be active in their lives. A 30-minute walk or some type of physical activity will benefit them as the age. The text mentions a study done by Erickson and his colleagues in 2009 where they studied the effect of aerobic exercise on the hippocampus. They found that due to aerobic exercise it produced greater volume in the hippocampus. This is significant because the hippocampus is the part of the brain that is responsible for memory, emotions, and spatial functioning. The body does not only need physical activities to produce healthier cognitive functioning but also nutrients. The text identifies three nutrient biomarker patterns that are significant on the aging brain. These nutrients are vitamin B, C,D, and E, omega-3, and trans fat. the foods that belong to these nutrients are beneficial to the brain. Older adults should make an effort to include these nutrients into their diets. positive impacts these nutrients make are better cognitive functioning and greater brain

Running increases blood flow to the brain including the hippocampus, the key area affected by Alzheimer’s disease.

In the book Spark, written by Dr. John J. Ratey, he discusses how exercise can positively affect how your brain works. He provides studies and personal experiences to support the claims he makes. I always knew exercise would improve your life but never could have imagined how much it can affect your brain health as well. The chapter I thought spoke the most to me was chapter two, Learning: Grow Your Brain Cells.

Exercise may benefit the brain by increasing blood and oxygen flow due to its known cardiovascular benefits since the head and heart seem to have a connection when conditions like high blood pressure, diabetes and high cholesterol have been linked to increase the risk of developing Alzheimer’s (Alzheimer’s Association, 2016). Furthermore, treatment is available as of today that may temporarily help memory and thinking problems, but this medications do not treat the origin of

Remember the treadmill that’s been unused for months and collecting dust in your basement? Well, except for maybe the first month after you bought it. Turns out, you might want to consider getting back on it if you want to keep your memory fresh and young. Researchers of the CARDIA study have found that there is a positive correlation between cardiorespiratory fitness at a young age and and improved cognitive capacity that lasted for 25 years.

There is ample evidence to demonstrate that through the normal ageing process alterations to the brain in structure and function are directly related to cognitive changes (Glisky, 2007). With an increasing ageing population strategies for prevention of disease and age related cognitive decline are necessary to improve quality of life and reduce the associated healthcare costs (Australian Government Productivity Commission [AGPC], 2013). Physical exercise is known to be crucial in maintaining physiological health; it can also be used as a means of neuroprotection and assist in modifiable risk factors for improved brain health and subsequent cognitive function. This review will critically analyse current research into the effects of exercise

The human brain is constantly changing where many new neurons are formed while others neurons die and new synapses are created while other synapses are removed (Spalding et al., 2013). Some dendrites will withdraw while other dendrites continue branching (Killgore et al., 2013). The processes driving the reshaping of the brain are neuroplasticity and neurogenesis. Neuroplasticity is the brain’s lifelong ability to rewire neural connections to compensate for diseases and injuries or in response to changes in the environment, whereas neurogenesis is the ability to create new neurons and neural connections. This dynamic process of remodeling gray matter is determined mainly by a person’s genetics and can slow down due to age (Denes, 2016). However, recent scientific evidence demonstrates other non-genetic factors that can significantly improve the development of the brain and slow down neurodegeneration (Kays et al., 2012). Physical exercise has always been linked to a person’s physical health, but many recent scientific studies shows physical exercise can also keep a person’s brain sharp. Exercise affects the brain in numerous ways by creating a flourishing environment for brain growth, aiding the release of numerous hormones, and fighting against depression, stress, and anxiety.

One of the most popular New Year’s Resolutions is making it to the gym and shedding off those extra unwanted pounds padded on from the end-of-year holidays that encourage over-indulgence of delicious treats and tasty comfort foods. This and many other unhealthy habits can lead to depression, anxiety and a reduced sense of self-worth. What most people do not realize is that the temptations can be lessened by having a better understanding of their brain health and its power. “Everything you are and everything you do is controlled by your brain” (Sharpbrains, 2014). Luckily, there is still hope for all of us to improve and repair our brains.

In recent years brain training games have become a topic of interest among both researchers and common people alike. Researchers are interested in the healing properties of brain training while normal people are looking to brain training as a way to improve their performance and get a leg up on the competition in school, work, and life. Up until recently, it was believed that the brain was unchangeable in terms of memory capacity. Researchers were well aware of the fact that the brain can change and form new connections when brain damage occurs. However, the idea that humans can train their brains to be more efficient and stronger seemed like a far-fetched cry from reality up until the late 1990’s (Weicker, Villringer & Thöne-Otto, 2016). As time went on and more research was conducted in the field of brain training, it became clear that brain training is not an exact science but, it does have real cognitive benefits.

The articles by Erikson et al., Gatz, Korol et al., and Draganski et al. explore the concept of increased physical activity and/or mental activity having effects on the cognitive function and development or deterioration of the brain as we age. Although I agree that physical exercise is critical in increasing cognitive function because of the health benefits it provides, as well as the increased blood flow and circulation throughout the body, I ultimately believe that a healthy brain is not achieved solely by physical exercise or mental exercise, but both. I think there is a link between physical and mental exercise, and that the combination of these two activities creates higher cognitive functioning of the mind as well as the body. The mind and body come together and meet to make an overall healthy individual.
